Bones of the appendicular skeleton : Upper Limb

Bones of the appendicular skeleton : Upper Limb

1. Structural Organisation

   • Bones of the upper / lower limb and those which connect them to the trunk
   • Two bones connect each upper limb, together = Pectoral Girdle
   • Two coaxial bones plus sacrum and coccyx = Pelvic Girdle

2. Pectoral (Shoulder) Girdle

   • Clavicle
     • Articulation points
       • Acromial end
       • Sternal end
   • Scapula
     • Articulation points
       • Acromion
       • Glenoid fossa
     • Multiple muscle attachment sites
   • Position pf the shoulder joint
   • Help move the upper limb
   • Provide a base for muscle attachment
